Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
barcode_generate ~87
Generate a standalone barcode (SVG text or PNG image). Supported types include code128, code39, ean13, upca, upce, itf14, msi, qrcode, datamatrix, pdf417.
| Name | Type | Req | Description |
|---|---|---|---|
| data | string | yes | Data to encode |
| format | string | – | – |
| type | string | yes | Barcode type, e.g. code128 |
No output schema declared.
No examples provided.
convert_zpl_dpi ~113
Rescale ZPL coordinates between printer resolutions (203/300/600 dpi). Embedded ^GF/~DG bitmap data is NOT rescaled — when present, a Warnings block precedes the output instead of silently passing.
| Name | Type | Req | Description |
|---|---|---|---|
| source | integer | – | Source resolution in dpi (152, 203, 300 or 600) |
| target | integer | – | Target resolution in dpi (152, 203, 300 or 600) |
| zpl | string | yes | Raw ZPL code to convert |
No output schema declared.
No examples provided.
cpcl_validate ~46
Lint/validate CPCL label code and return the structured diagnostics report (findings with positions and severity) as JSON.
| Name | Type | Req | Description |
|---|---|---|---|
| cpcl | string | yes | Raw CPCL code |
No output schema declared.
No examples provided.
epl_validate ~50
Lint/validate EPL/EPL2 label code and return the structured diagnostics report (findings with positions and severity) as JSON.
| Name | Type | Req | Description |
|---|---|---|---|
| epl | string | yes | Raw EPL/EPL2 code |
No output schema declared.
No examples provided.
explain_zpl ~196
Human-readable health REPORT for a finished ZPL label with a 0-100 score, sectioned (syntax, size/DPI, orientation, barcodes, fonts, memory): only assessable sections count, the rest say 'not assessed'. Use it to review or explain a label to a person; for a quick pass/fail check while editing use zpl_validate. Pass the real label size — findings depend on it.
| Name | Type | Req | Description |
|---|---|---|---|
| dpmm | integer | – | Printer density in dots per mm (6, 8, 12 or 24) |
| height_in | number | – | Label height in inches (at most 15) |
| model | string | – | Optional printer model as manufacturer/model (e.g. zebra/zd421) to add a model-compatibility section |
| width_in | number | – | Label width in inches (at most 15) |
| zpl | string | yes | Raw ZPL code |
No output schema declared.
No examples provided.
language_detect ~68
Detect which printer language raw label code is written in (ZPL, EPL, TSPL or CPCL). Heuristic: returns the language plus a confidence TIER (high/medium/low) and signal codes — not a probability.
| Name | Type | Req | Description |
|---|---|---|---|
| code | string | yes | Raw label code to classify |
No output schema declared.
No examples provided.
tspl_validate ~54
Lint/validate TSPL/TSPL2 label code and return the structured diagnostics report (findings with positions and severity) as JSON.
| Name | Type | Req | Description |
|---|---|---|---|
| tspl | string | yes | Raw TSPL/TSPL2 code |
No output schema declared.
No examples provided.
zpl_command_help ~108
Look up one ZPL command in the maintained catalog: name, syntax, parameters (types, ranges, defaults) and whether the preview engine actually renders it — printer-side commands are honestly marked as not rendered.
| Name | Type | Req | Description |
|---|---|---|---|
| command | string | yes | Command code with or without prefix, e.g. ^PO, BC, ~DG |
| locale | string | – | Language for the name and descriptions (default English). Command codes, syntax strings, examples and parameter names are protocol and never change. |
No output schema declared.
No examples provided.
zpl_compatibility ~102
Compatibility RISK analysis of ZPL code against a specific printer model, given as manufacturer/model (e.g. 'zebra/zd421'). NOT an emulator and never says 'it works': reports the model's language posture with evidence level, size-rule findings and the scope of our preview.
| Name | Type | Req | Description |
|---|---|---|---|
| model | string | yes | Printer model as manufacturer/model, e.g. zebra/zd421 |
| zpl | string | yes | Raw ZPL code |
No output schema declared.
No examples provided.
zpl_preview ~142
Render ZPL label code to a PNG image via the Labelixa API. This is a SERVER-SIDE render for inspection — it is not a guarantee of how a specific physical printer will output the label.
| Name | Type | Req | Description |
|---|---|---|---|
| dpmm | integer | – | Printer density in dots per mm (6, 8, 12 or 24) |
| height_in | number | – | Label height in inches (at most 15) |
| index | integer | – | Which label to render when the stream contains several |
| width_in | number | – | Label width in inches (at most 15) |
| zpl | string | yes | Raw ZPL code (^XA ... ^XZ) |
No output schema declared.
No examples provided.
zpl_validate ~151
Pass/fail lint for ZPL: machine-readable diagnostics with line/column, code and severity (unknown commands, parameter range errors, layout overflow). Fast; run it before zpl_preview whenever you generate or edit ZPL. For a human-readable report with a score use explain_zpl instead. Pass the real label size — checks depend on it.
| Name | Type | Req | Description |
|---|---|---|---|
| dpmm | integer | – | Printer density in dots per mm (6, 8, 12 or 24) |
| height_in | number | – | Label height in inches (at most 15) |
| width_in | number | – | Label width in inches (at most 15) |
| zpl | string | yes | Raw ZPL code |

What is the Labelixa MCP server?
Labelixa is an MCP server listed in the public MCP registry as com.labelixa/zpl. Thermal label MCP server: render, validate, debug and convert ZPL, EPL, TSPL and CPCL labels. This page covers its npm package (labelixa-mcp).
Is the Labelixa MCP server safe to use?
Labelixa scores 85 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 6 November 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Labelixa MCP server expose?
Labelixa exposes 11 tools: zpl_preview, zpl_validate, barcode_generate, language_detect, epl_validate, and 6 more. Their descriptions and schemas cost roughly 1,117 tokens of context every time the server is loaded.
Is the Labelixa MCP server still maintained?
Labelixa is still listed as active in the MCP registry. We last reached this channel on 6 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the Labelixa MCP server under?
Labelixa declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
What did VerifyMCP test on the Labelixa MCP server?
VerifyMCP ran 16 checks on Labelixa, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
